AD9467SCPZ-250-EP

Analog To Digital Converters (ADC) Overview

The AD9467SCPZ-250-EP is a 16-bit, monolithic, IF sampling analog-to-digital converter (ADC) from Analog Devices. It operates at a maximum conversion rate of 250 MSPS and features an integrated input buffer with a programmable differential full-scale input range of 2 V p-p to 2.5 V p-p. The device delivers a typical signal-to-noise ratio (SNR) of 75.5 dBFS at 210 MHz input and a spurious-free dynamic range (SFDR) of 90 dBFS up to 300 MHz. It utilizes LVDS-compatible outputs and requires 1.8 V and 3.3 V power supplies. Designed for high dynamic range applications, it includes a clock duty cycle stabilizer and serial port interface control.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against the manufacturer's current ordering guide to confirm package options and RoHS compliance status. Ensure that the extended temperature rating aligns with the environmental requirements of the target deployment. Cross-reference the datasheet revision history for any updates to electrical specifications or pin configurations prior to finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring high linearity and wide bandwidth at intermediate frequencies. The integrated buffer simplifies front-end design by reducing the need for external amplifiers. Consider the 1.8 V and 3.3 V dual-supply requirement during power budgeting. Verify that the LVDS output interface matches the receiving logic levels of the downstream FPGA or processor.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9467-EP enhanced product family, which is optimized for defense and aerospace environments. It shares the core architecture of the commercial AD9467 but undergoes stricter manufacturing controls. The EP variant ensures long-term availability and reliability for critical infrastructure and military applications where standard commercial parts may not suffice.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9467SCPZ250EPRL7 is a reel-packaged version of the same device. Direct functional replacements within the same family include other AD9467 variants with different sampling rates, provided the system timing allows for adjustment. No alternative manufacturers offer a direct pin-compatible substitute with identical enhanced product specifications.
